X=3

Explanation:

A straight line equals 180°, and they give you the one angle of 56°, so you know 56+ the other equation has to equal 180

56+4x+112=180
168+4x=180

Subtract 168 from both sides

4x=12

Divide 4 from both sides

X=3

You can check by filling it in.

56+4*3+112=

12+56+112=180

Paraphin [41]

Answer:

$5.60

Step-by-step explanation:

interest = 3.5% = 3.5 ÷ 100 = 0.035

So 3.5% of $400 = 0.035 x 400 = $14

If Jonah spend 3/5 of the interest, then he gives his brother 2/5 of the interest each year.

2/5 of $14 = 2/5 x 14 = $5.60
